Objective:To explore the current status of self-disgust in female breast cancer patients and analyze its influencing factors, so as to provide reference for clinical intervention.Methods:Convenience sampling was used to select 283 female breast cancer patients who were hospitalized in Guangdong Provincial Hospital of Chinese Medicine from June to July 2024 for the study. A questionnaire survey was conducted using the General Information Questionnaire, Questionnaire for the Assessment of Self-Disgust (QASD), Family Avoidance of Communication about Cancer Scale, Body Image Scale, and the Chinese version of the Female Self-Advocacy in Cancer Survivorship. Factors influencing patients' self-disgust were analyzed using one-way analysis of variance and multiple linear regression.Results:The total score of QASD in female breast cancer patients was (33.77±7.64). Education level, sexual dysfunction after breast cancer, family avoidance of communication about cancer, body image and self-advocacy were influencing factors of self-disgust in female breast cancer patients ( P<0.05) . Conclusions:Self-disgust of female patients with breast cancer is at a medium to high level. It is recommended that nurses pay attention to the psychological status of patients with low level of education and sexual dysfunction after the disease, implement targeted psychological interventions to improve the family avoidance of communication about cancer and body image, and increase the awareness of self-advocacy, thus reducing the risk of self-disgust in female breast cancer patients.

OBJECTIVE To explore the mechanism by which gastrodin improves renal hyperten-sion in rats.METHODS A rat model of renal hypertension was established by ligating the renal artery.seventy-five rats were randomly divided into 5 groups(n=15):control group(sham operation group),model group,model+ramipril 1 mg·kg-1,model+gastrodin 100 and 200 mg·kg-1.The systolic blood pressure of the tail artery after modeling>18.12 kPa was regarded as the success of modeling.After the model was established,rats in the model+ramipril group were ig given ramipril 1 mg·kg-1 while the model+gastrodin group was ig given gastrodin 100 and 200 mg·kg-1 respectively for 4 weeks.Colori-metric assay kit was used to detect the serum superoxide dismutase(SOD)activity and malondialde-hyde(MDA)content in rats.ELISA was used to detect serum angiotensin-2(Ang-2)and aldosterone(ALD)contents,as well as serum and thoracic aortic tissue interleukin-1β(IL-1β),IL-6 and tumor necrosis factor α(TNF-α)content.HE staining was performed to detect pathological changes in thoracic aorta tissue of rats.The expressions of autophagy protein miceotubule associated protein light chain 3(LC3)-Ⅱand LC3-Ⅰwere detected by Western blotting.RESULTS The systolic pressure of the tail artery of rats after modeling exceeded 18.12 kPa,indicating that the modeling was successful.Compared with the control group,the contens of Ang-2(P<0.01)and ALD(P<0.01)in the model group were significantly increased,the activity of SOD(P<0.01)in serum and thoracic aorta tissue was significantly decreased,the content of MDA(P<0.01)was significantly increased,the contents of IL-1β,IL-6 and TNF-α in serum and thoracic aorta tissue were significantly decreased(P<0.01)and the ratio of LC-32/LC-31 in thoracic aorta tissue was significantly increased(P<0.01).Compared with the model group,gastrodin significantly increased the systolic pressure of the tail artery(P<0.01),the contents of Ang-2(P<0.01)and ALD(P<0.01)and the activity of SOD(P<0.01)in serum,as well as decreased the contents of MDA,IL-1β,IL-6 and TNF-α(P<0.01)in serum and thoracic aorta tissue.Meanwhile,gastrodin signifi-cantly decreased the ratio of LC3-Ⅱ/LC3-Ⅰ in rat thoracic aorta(P<0.01).CONCLUSION Gastrodin can improve the blood pressure of renal hypertensive rats,and the mechanism is possibly related to the reduction of autophagy protein LC3-Ⅱ/LC3-Ⅰratio.

Objective:To retrieve and summarize the evidence of indications for extubation in neurosurgical tracheotomy patients, so as to provide reference for promoting timely and safe extubation of neurosurgical tracheotomy patients.Methods:Evidence-based problems were identified according to the population, intervention, professional, outcome, setting, type of evidence (PIPOST) model. According to the "6S" classification model of the evidence-based retrieval database, all evidences of extubation indications of neurosurgical tracheotomy patients in the database, guideline website and professional institution website were systematically retrieved, including clinical guidelines, systematic review, expert consensus, evidence summary and clinical decision-making. The search period was from the establishment of the database to May 31, 2022. Two researchers independently evaluated the quality of the included article and extracted evidence.Results:A total of 12 articles were included, including four guidelines, four systematic reviews, two expert consensuses, one evidence summary, and one clinical decision-making. A total of 18 pieces of best evidence for extubation indications of neurosurgical tracheotomy patients were summarized, including 7 themes: disease condition, consciousness and autonomous activity, respiratory function, cough function, swallowing function, airway condition, multidisciplinary team and equipment support.Conclusions:The extubation of neurosurgical tracheotomy patients should consider many factors. The summary of evidence has a certain degree of scientific and practical significance, which can provide evidence-based basis for medical and nursing staff to apply evidence in a targeted manner.

OBJECTIVE: To explore the prevalence and clinical manifestations of ring chromosomes among children featuring abnormal development. METHODS: From January 2015 to August 2021, 7574 children referred for abnormal development were selected, and their peripheral blood samples were subjected to G-banded chromosomal karyotyping analysis. RESULTS: Twelve cases of ring chromosomes were detected, which have yielded a prevalence of 0.16% and included 1 r(6), 2 r(9), 1 r(13), 1 r(14), 2 r(15), 1 r(21) and 3 r(X). The children had various clinical manifestations including growth and mental retardation, limb malformation, and congenital heart disease. For two children with r(9) and two with r(15) with similar breakpoints, one child with r(9) and one with r(15) only had growth retardation, whilst another with r(9) and another with r(15) also had peculiar facies and complex congenital heart disease. The r(X) has featured some manifestations of Turner syndrome. CONCLUSION Ring chromosomes are among the common causes for severe growth and mental retardation in children with diverse clinical phenotypes. Clinicians should pay attention to those with developmental anomalies and use chromosomal analysis to elucidate their genetic etiology.

The parallel chart records a HIV-positive patient，who initially declined treatment due to psychological reasons，however，with the support and care provided by both the medical team and his family members，he eventually accepted treatment actively and successfully reintegrated into society. The case indicates that healthcare professionals should not only treat the physical conditions of patients，but also give them the warm humanistic concern and care.

Objective:To analyze the distribution and drug resistance of wound pathogenic microorganisms in outpatients of wound healing center so as to provide a basis for the standardized construction of wound healing centers.Methods:A retrospective case series study was used to analyzed the data of 365 outpatients treated at Ruijin Hospital, Shanghai Jiaotong University School of Medicine from December 2017 to October 2019. There were 220 males and 145 females, aged (58.8±18.9)years (range, 18-98 years). The patients included 92 first-visit patients and 273 re-visit patients. The culture results (positive rate of pathogenic microorganisms, bacterial species, bacterial distribution) and drug sensitivity results of the wound secretions were compared and analyzed.Results:(1) Among 365 samples of wound secretions, 198 patients were positive for pathogenic microorganisms with a positive rate of 54.3%. A total of 107 strains (51.0%) of Gram-positive bacteria were detected, mainly Staphylococcus aureus (70 strains, 33.3%); 95 strains (45.2%) of Gram-negative bacteria were detected, mainly Escherichia coli (20 strains, 9.5%), followed by Pseudomonas aeruginosa (17 strains, 8.1%); 8 strains (3.8%) of fungi were detected. (2) A total of 26 (28.3%) first-visit patients were positive for pathogenic microorganisms, and 172 (63.0%) re-visit patients were positive for pathogenic microorganisms. The rate of positive microorganism detection had significant differences between first-visit and re-visit patients ( P<0.05). (3) A total of 29 strains were detected in first-visit patients, including 16 strains (55.2%) of Gram-positive bacteria, 11 strains (37.9%) of Gram-negative bacteria and 2 strains (6.9%) of fungi. A total of 181 strains were detected in re-visit patients, including 91 strains (50.3%) of Gram-positive bacteria, 84 strains (46.4%) of Gram-negative bacteria and 6 strains (3.3%) of fungi. The microbial distribution was significantly different between first-visit and re-visit patients ( P<0.05). (4) Compared with first-visit patients, the resistance of Staphylococcus aureus isolated from the re-visit patients to spenicillin, oxacillin, ciprofloxacin, tetracycline, clindamycin, moxifloxacin, erythromycin, and levofloxacin were increased variably. No vancomycin-resistant Staphylococcus aureus was detected, indicating that the staphylococcus aureus presented in the wound was highly sensitive to vancomycin. Conclusions:Staphylococcus aureus is the most common microorganism in wound secretions in outpatients of wound healing center. The rate of positive pathogenic microorganisms in wound secretions of re-visit patients is significantly higher than that of first-visit patients, and the distribution of pathogenic microorganisms of first-visited and revisited patients differs significantly. The Staphylococcus aureus detected in re-visit patients has a higher resistance to common antibiotics compared with first-visit patients. It is suggested that timely detection of pathogenic microorganisms in outpatients and effective control and supervision of outpatient infections are important contents that cannot be ignored in the construction of wound healing center.

Objective: To explore the effects of delayed umbilical cord clamping on full-term newborns and maternal outcomes. Methods: From January 2017 to April 2018, 287 normal full-term newborns delivered by vagina in the First People's Hospital of Xiaoshan District were selected in the research, and randomly divided into the control group (141 cases) and observation group (146 cases) according to the order of entering the delivery room.The control group was ligated the umbilical cord 15-20 s after delivery, while the observation group was ligated the umbilical cord 60 s after delivery.The level of hemoglobin, hematocrit, the incidence of anemia, polycythemia, hyperbilirubinemia and phototherapy time of full-term newborns were compared between the two groups 3 days after birth.The third stage of labor, the amount of postpartum hemorrhage and the incidence of postpartum hemorrhage were compared between the two groups. Results: The hemoglobin[(181.49±16.84) g/L] and hematocrit (0.545±0.055) in the observation group were significantly higher than those in the control group[(175.90±17.49 )g/L, (0.515±0.062)] at the third day after birth (t=2.748, 3.409, all P<0.05). The incidence of neonatal anemia in the observation group was 0.68% (1/146), which was significantly lower than that in the control group [4.96% (7/141)], and the difference was statistically significant (χ²=4.848, P<0.05). The incidence rates of neonatal polycythemia, hyperbilirubinemia and phototherapy time in the observation group were 2.05% (3/146), 24.66% (36/146), (65.50 ±14.63)h, respectively, which in the control group were 0.17% (1/141), 22.70% (32/141) and (62.09±14.40)h, respectively, there were no statistically significant differences between the two groups (χ²=0.945, 0.153, t=0.953, all P>0.05). The third stage of labor time, postpartum hemorrhage volume, incidence of postpartum hemorrhage in the observation group were (5.97 ±4.17)min, (239.04±69.15)mL, 2.05% (3/146), respectively, which in the control group were (5.84±3.62)min, (227.73±56.99)mL, 0.71% (1/141), respectively, there were no statistically significant differences between the two groups (t=0.281, 1.504, χ²=0.945, all P>0.05). Conclusion Delayed umbilical cord clamping can increase the level of hemoglobin and hematocrit in newborns, reduce the incidence of anemia in newborns, and without increasing postpartum hemorrhage.

Objective To explore the relationship between chromosomal abnormalities and diseases in children by analyzing chromosome karyotypes. Methods The chromosome karyotype analysis of peripheral lymphocytes in 5 329 children was performed. Results In all, abnormal karyotype were found in 1 723 cases (32.33％) , in which the numerical chromosome abnormalities were detected in 1 539 (89.32％) , following by 125 cases of structural chromosome abnormalities (7.25％) , 53 cases of sex reverse syndrome (3.08％) , and 6 cases of true hermaphroditism (0.35％). The chromosome polymorphism were detected in 228 cases (4.28％). Conclusions The numerical chromosome abnormalities is most frequent chromosomal aberration and is one of the important causes that result in mental retardation, growth delay and disorders of sex development in children.

Objective To analyze the effect of transport and storage conditions on the detection of pathogenic nucleic acid MHV, Reo-3, MNV in laboratory mouse cecal contents samples. Methods MHV, Reo-3 and MNV were mixed with mouse cecal contents and used as reference samples,respectively. They were placed in the lysis buffer of RNA extraction reagent(buffer AVL)or normal saline, and stored at 4℃ and room temperature(22℃-25℃). RNA of these samples was extracted at 1,2,3,7,and 14 days. Then the amount of nucleic acid in samples was detected by real-time fluorescence quantitative PCR. Results A greater decrease of the amount of nucleic acid was observed when the samples were placed in normal saline than that kept in buffer AVL. The amount of nucleic acid in samples stored at 4℃ was found to be higher than that stored at 25℃ room temperature. The amount of nucleic acid in the samples which were kept in buffer AVL at 4℃ for 3 days was higher than 50%,still detectable in the samples kept for 7 days,and undetectable at 14 days. Conclusions Mouse cecal content samples are preferably stored in the lysis buffer of RNA extraction reagent and transported at 4℃ for the detection of MHV, Reo-3, and MNV nucleic acid. It is better to complete the detection test within 3 days.
